Abstract :
A new embedded structure with an annular ring and a cylindrical dielectric resonator excited by means of a coaxial probe has been realised and investigated experimentally to obtain a large bandwidth enhancement. The return loss, radiation patterns, and antenna gain of this configuration are presented. The capability of such an antenna, with a low profile (a/h=6) and 10 dB impedance bandwidths of 32 and 38%, is demonstrated
